Goat farming is a significant activity in the Brazilian Northeast, characterized by family and subsistence production, with low levels of technology and technical assistance, as per. Technological problems, especially those related to animal health, affect the productivity and profitability of goat farming. Caseous lymphadenitis (CL) is an infectious disease, distributed worldwide, Corynebacterium pseudotuberculosis is an etiological agent, and is one of the main diseases that compromise the health of livestock, affecting males and females of goats and sheep regardless of breed and age, being most commonly found in animals from one year of age onwards. It does not present specific symptoms, in most cases, however, it results in low animal productivity and reproductive efficiency, as it is a chronic disease. With an estimated clinical prevalence of 50% in Brazil, especially in the Northeast, CL affects the reproductive efficiency of goats, as it can cause infertility in females, in addition to hormonal imbalances. Investigating the impacts of CL on reproduction and the search for alternatives to minimize losses, such as pharmacological control of the estrous cycle, are essential to improve the situation of herds.
